Neutralisation – Classification of Salts

Neutralisation Reaction When solutions of acids and bases are mixed, reactions occur in which the acidic and basic properties of the reactants are nullified. Such acid-base reactions are known as neutralisation reactions. The Reactions of Acids The reactions of acids with metal hydroxides, metal oxides, carbonates and hydrogen carbonates can all be considered acid-base reactions...

Gravimetric Determination of Sulfate Content

First-Hand Investigation – Determination of the Sulfate Content (Gravimetric Determination) of a Lawn Fertiliser The sulfate content of ammonia fertiliser can be determined gravimetrically by converting the sulfate in a weighed sample of fertiliser to barium sulfate. The highly insoluble barium sulfate is collected, dried and weighed of Gravimetric Determination. Dissolve 1.00 g of fertiliser...

Particle Theory of Matter

Particle Theory of Matter Matter Particles All matter is composed of tiny particles. These particles interact with one another through collisions and vibrations. These particles can be elements, molecules or compounds. In different states the particles of the substance interact differently. Particle Nature of Gases The kinetic theory of gases is used to predict the...
